A unique discovery of submerged man-made structures on the seabed off Orkney could help find solutions to rising sea levels, experts have said.
They said the well preserved stone pieces near the island of Damsay are the only such examples around the UK.
It is thought some of the structures may date back thousands of years.
Geomorphologist Sue Dawson said that people have survived and adapted in the past and it is that adaption to climate change that needs to be learned from.
One of the team, archaeologist Caroline Wickham-Jones, of the University of Aberdeen, said of their freezing investigations under the December seas off Orkney: "We have certainly got a lot of stonework. There are some quite interesting things. You can see voids or entrances.
